Fig. 11 is a detached view of one of the bearings for one of the Fig. 12 is a view showing the relative position of the feed-rolls, also the forming-dies, their shafts, and cylinders, and illustrating the position of one set of folding-dies and illustrating a sheet of metal in proper relative position with refer once to the various dies. Fig. 13 is a view showing the finished product.

The present invention has relation to sheetmetal-edging machines; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the draw ings.

In the accompanying drawings, 1 represents the frame, which may be of the form shown and is provided with suitable housings, such as 2, which housings are for the purpose of providing means for holding the various shafts in proper relative position. To the rent or forward portion of the frame 1 is connected or formed integral therewith the table 3, which table is'for the reception of the sheets of metal designed to be passed through the machine, and, as illustrated, said table is provided with the guide-bars 4, which guide-bars are adjustably connected to the table in any convenient and well-known manner. At the inner edge of the table 3 and in proper position to receive the sheets of metal the feed-rollers 5 and G are located, one directly above the other, and are so connected to the shafts '7 and Sthat they will rotate with said shafts, which shafts are driven in opposite directions by means of the pinions 9 and 10. Directly back of the feed-rollers 5 and 6 and in horizontal alinement therewith are located the right and left hand screw-threaded shafts 11 and 12, which shafts are propelled in opposite directions by means of the pinions 13 and 14, the pinions 9, 10, 13, and 14 all being driven by the pinion 15, which pinion is mounted upon the shaft 16. Upon the right and left hand screw-threaded shafts 11 and 12 are located the cylinders 17 and 18, said cylinders being provided with non-screw-thr'eaded apertures. At the end of the cylinder 18 is located the die 19, and at the end of the cylinder 17 is located the die 20, said die being located upon the opposite ends of the cylinders 17 and 18, and are so located for the purpose of bending at right angles to the feed flanges upon opposite sides thereof, said dies 19 and 20 being spaced one from the other the distance between the flange edges of the sheet. For the purpose of holding the dies in proper fixed position their apertures are screw-threaded, said dies abutting against the ends of the cylinders 17 and 18.

It will be understood that in order to form flanges upon sheets of metal having diiferent widths the dies 19 and 20 must be adjusted to or from eachother, and in order to so adjust the dies filling cylinders or rings, such as. 21, are provided, which rings are strung upon the shafts 11 and 12 and are formed of different widths, so as to provide the proper adjustment for the dies 19 and 20. It will be understood that by locating the dies 19 and 20 as shown right angled flanges will be guide-flanges 22 are provided, it being under- I stood that a guide-flange is to be located forj each edge of the sheets, or, in other words, two guide-flanges, such as 22, are to be provided. For the purpose of properly folding.

the right-angled flanges formed upon the sheets, soas to provide hooked edges, the

horizontal dies 23, 24, 25, and 26 are provided, and are located substantially as illustrated in Fig. 7, and, as illustrated, the die 24 is upon the bottom or underside of the sheet,

the die upon the top side of the sheet, and

the grooved dies 23 and 26 located in opera: tive relation to the dies 24 and 25,

- It will be understood that in order to properly fold the edges of the sheet, or, in other words, to bend the right-angled flanges of the sheets into proper position to form hooked edges, power should be applied to all of the dies, and in order to so apply power each die must be provided with a driving-shaft, the die 23 being driven by the shaft 27, the die 25 by the shaft 28, the die 24 by the shaft 29, and the die 26 by the shaft 30, power being applied to said shafts by means of suit-v able beveled gear-wheels 31 and 32, the beveled gear wheels 31 being fixed upon the shaft 33 and said shaft provided with the beveled wheel 34. The beveled gear-wheel is driven by the shaft 35 and the beveled gearwheel 36, said shaft being driven by means of the shaft 37 and the gear-Wheels 33 and 39.

It will be understood that the shafts 29 and 30 are driven by beveled gear-wheels, such as 31 and 32, the arrangement of said beveled wheels being substantially the same and are not illustrated, as they are simplya duplica- To the upright memtion of the ones shown. hers 40 are connected the screwthreaded shafts or bars 41 and 42, said screw-threaded shafts or bars being formed in pairs and one.

pair located directly above the other, and each shaft or bar is provided with screw-threaded collars 43, which screw-threaded collars are for the purpose of holding in proper position the bearing-blocks 44, which bearing-blocks are for the purpose of holding in proper p0 sition the die-shafts 27 and 28.

It will be understood that by providingthe screw-threaded shafts or bars 41 and42 and locating the screw-threaded collars 43 thereon the bearing-blocks 44 can be moved or adjusted so as to bring the shafts 27 and 28, together with their dies 23 and 25, to or from each other, and thereby provide adjustment for different widths of sheets. It will of course be understood that in order'to adjust the shafts 29 and 30, together-with their dies 24 and 26., a duplication of the mechanism employed in adjusting the shafts 27 and 28, together with their dies, must be employed,

and a description of the lower devices for supporting and holding in proper position the lower die-shafts is unnecessary here. The main power-shaft 45 is provided with a driving-pulley, such as 46 or its equivalent, and the main pinion 47, properly connected or mounted upon the power-shaft, imparts rotary motion to the wheel 48, said wheel imparting motion to the wheel 49 and the pinion imparting motion to the wheel 50, said wheels being mounted upon shafts so arranged and located that proper rotary motion will be imparted to the various rotary parts of the machine proper. In Fig. 12 the dieshaft 27 is illustrated, together with the up per set of the lower screw-threaded bar, said bars being shown only in part. The bracket= arm 51 is shown placed in position upon the screw-threaded bars 52, said bracket being for the purpose of holding in proper adjustment the head 53, which head is provided with a slot 54, which slot is for the purpose of providing means for adjusting the block 55 up and down, to which block the guide members 22 and 22 are attached.

It will be understood that a clamping bolt,

such as 56, should be employed to hold the block 55 in proper fixed adjustment. The bracket arm 51 should be formed in .two pieces, so that the block 53 can be clamped in fixed position by means of a clamping-bolt 57.

For the purpose of binding the cylinders 18 and 17 and at the same time preventing said cylinders from moving endwise upon the shafts 11 and 12 the die-collars 20 are provided, and for the purpose of rotating the die collars 20 and the dies 19 and 20 they are each provided with suitable apertures 21, into which apertures a bar may be inserted for the purpose of rotating the same for any purpose. The folding-dies 23 and 26 are provided with grooves 23 upon their peripheries, and

the dies 24 and 25 are provided with flanges 26, said grooves and flanges corresponding in shape with each other and the flanges located in the grooves, substantially as shown in Figs. v5, 6, 7, and 8.
